Interesting pulp fiction by Hubbard; I don't recall ever reading the adventures of Africa, except for the movie "Zulu" many years ago.
A man who lets nothing stop him in getting a railroad from one country to another, to open a route through the Nile, is met by a lovely blonde, two characters who want him to fail, and a tribe of cannibals who would like nothing better than to make him their next meal.
Slow start, but a fun read. Even though these stories are over 60 years old, there is a cadence, a rhythm to them that keep even a modern readers' interest.
Recommended.
